Donald Trump’s official campaign account was briefly blocked from posting on Twitter on Wednesday. Twitter claimed that a post by the campaign was misleading and violated its service terms.While Trump did retweet the post on his personal account, he did not have his access revoked.The campaign resumed access to the account later on Wednesday.Meanwhile, Facebook has deleted a post by President Donald Trump for the first time, saying it violated its policy against spreading misinformation about the coronavirus.The post in question featured a link to a Fox News video in which Trump says children are “virtually immune” to the virus. Facebook said in a statement Wednesday that the video includes false claims that a group of people is immune from COVID-19.It says that is a violation of its policies around harmful COVID-19 misinformation. 851
Dr. Anthony Fauci said during an interview on Wednesday that a World Health Organization expert was “not correct” for stating that coronavirus infections from those who are asymptomatic are “very rare.”Dr. Maria Van Kerkhove, a World Health Organization’s infectious disease expert, walked back her comments from Monday one day later, qualifying her statement by saying it’s not the official policy of the WHO."I used the phrase 'very rare.' I think that's misunderstanding to state that asymptomatic transmission globally is very rare. What I was referring to was a subset of studies," Van Kerkhove said during a press conference on Tuesday. "I was just trying to answer a question at a press conference, I wasn't stating a policy of the WHO or anything like that."While the majority of coronavirus cases come from those who are symptomatic, Fauci said on ABC’s “Good Morning America” that the spread from those who are asymptomatic is not uncommon."The evidence that we have given the percentage of people, which is about 25, 45-percent of the totality of infected people, likely without symptoms," he said. "And we know from epidemiological studies that they can transmit to someone who is uninfected, even when they're without symptoms. So to make a statement to say that's a rare event was not correct."On Monday, Dr. Ashish Jha, the director of Harvard's Global Health Institute, took issue with Van Kerkhove's anaylsis"Asymptomatic spread is the Achilles heel of this outbreak," Jha tweeted. "Both asymptomatic and pre-symptomatic spread huge problem for controlling disease because folks shedding virus while asymptomatic pre-symptomatic has one advantage: You can use contact tracing to find folks they infected. But that doesn't help prevent pre-symptomatic spread"Jha cited a May Swiss study that indicated that between 40 and 60% of all coronavirus cases originated from people when they didn't have symptoms at the time of the spread.The debate comes as a number of states are continuing to see an increase in coronavirus cases. Most notably is Arizona, which has advised hospitals to be prepared to expand intensive care units in order to accommodate the influx of coronavirus patients. 2208

EL CAJON, Calif. (KGTV) -- Students in the Grossmont Union High School District will head back to class on Monday, Aug. 10, but the start of the new school year comes with a number of changes.For starters, all classes will be online because of the coronavirus pandemic.The district will also have new leadership, as Superintendent Theresa Kemper takes over."We have a plan that's scalable and flexible," Kemper told ABC 10News.Kemper took over as the superintendent on July 1 after Tim Glover left the position. Kemper has been with the district for nearly 25 years, with stints as an assistant principal, principal and assistant superintendent.Since May, Kemper has been leading the effort to create a back to school plan for this fall amidst the pandemic."We knew it was not entirely in our control which is exactly why we created the plan the way we did," she said. "We're committed to moving into it slowly and carefully and not making mistakes as we go."According to their "Roadmap for Reopening," GUHSD will start the 2020-21 school year entirely online, complying with state and county health guidelines that say schools cannot return to in-person learning until San Diego County has been off the state coronavirus watch-list for 14 days.The full plan calls for five levels of reopening that gradually increase the number of students on campus. Level 2 allows for 25% capacity and Level 3 is 50%; Level 4 is 100% capacity, with some limited online learning. Level 5 is a return to full, in-person school.Kemper said the goal is to ease teachers and students back into the classroom, and allow for flexibility as things change."It's been a long time since teachers and students have been in classrooms together," she said. "So, we want to ease them into the process and make sure conditions are still holding for them to all be there."In response to the plan, the Grossmont Education Association, which represents the teachers in the district, released a statement on their Facebook page on July 2. It says, in part, that the changes for the coming school year "reflect our ongoing commitment to innovation and learning for all students."The statement concludes by saying, "While there are many, many other issues and details that still need to be determined, we are excited to move forward with our plans to prepare to have students on campus this fall."Teachers, meanwhile, spent the summer training and adapting their lesson plans to what Kemper calls "distance learning 2.0.""It's more interactive," she explained. "We'll have daily interaction with students and teachers. More hands-on experiences for students, more project based and more interactive learning."Grossmont also just completed million worth of construction projects. They were part of more than 0 million in voter-approved bonds since 2004.But the pandemic has left the new buildings empty and unused. They'll stay that way until students come back.Kemper said the new facilities will help the students readjust to the new normal."They're modernized, updated, better able to use the technology that is state-of-the-art," she said. "We have spaces for students that we didn't have, inside and outside."Even before the pandemic, the district gave every incoming student a Chromebook laptop and made them comfortable with online and digital learning. Kemper said that's helping students and teachers adapt to distance learning.Now, she's waiting to see what the new school year brings."We've never gone through this before and it's really challenging opening school in the midst of a pandemic," said Kemper. "But we've created a plan, we are opening school and I think it's going to be amazing." 3683
Dining out frequently is known to increase one's intake of unhealthy sugars and fats. But a new study suggests that there's another reason to eat at home more often: phthalates.Phthalates are potentially harmful chemicals found in hundreds of consumer products, including perfumes, hair sprays, shampoos and the plastics used in food processing and packaging.Consumption of these chemicals has?been linked to birth defects in young boys as well as behavioral problems and obesity in older children and adults. Exposure in utero can alter the development of the male reproductive tract, resulting in incomplete descent of one or both testicles.Scientists also suspect that the chemicals can disrupt hormones and may cause fertility problems. They've connected them to childhood obesity, asthma, neurological problems, cardiovascular issues and even cancer."Phthalates are a class of synthetic chemicals known as endocrine disruptors, meaning they affect hormones in the body," said Dr. Sheela Sathyanarayana, an associate professor of pediatrics at Seattle Children's Hospital and the University of Washington and past chairwoman of the Environmental Protection Agency's Children's Health Protection Advisory Committee, who was not involved in the study. "Hormones are essential for normal body functions such as reproduction or metabolism."The?study, published Wednesday in the journal Environment International, found that the phthalate levels of participants who had eaten at restaurants, cafeterias and fast-food outlets in the previous day were 35% higher than those who reported eating food purchased at the grocery store.Those who dined out were probably exposed to the chemicals via foods that had been in contact with plastic packaging, said Ami Zota, an assistant professor of environmental and occupational health at George Washington University and a leading author on the study."The main idea is that food that is made in restaurants and cafeterias may be coming into contact with materials containing phthalates in part because some portion of the food is made in decentralized locations," Zota said."Most of the phthalates that are of most concern from a health perspective are plasticizers; they're added to make plastics soft," she added. "They're added to food packaging, they can be in food handling gloves, and they can be found in food tubing."The study relied on data collected between 2005 and 2014 from the National Health and Nutrition Examination Survey, administered every two years by the US Centers for Disease Control and Prevention. It included 10,253 people who were asked about their dining habits over the past 24 hours and who provided urine samples to evaluate phthalate levels in the body.The researchers found that about two-thirds of respondents reported dining out at least once the previous day. Those who dined out also had significantly greater levels of phthalate metabolites in their urine.This association was consistent across all ages, genders and ethnicities, but it was strongest among teenagers who ate out: They had phthalate levels 55% higher than those who ate at home."The association between phthalate exposure and dining out existed in all age groups, but the magnitude of the association was highest for teenagers," Zota said. "Certain foods, especially cheeseburgers and other sandwiches, were also associated with increased levels of phthalates, but only if they were purchased from a dining-out establishment."This is not the first time phthalate levels have been linked to food sources. In 2016, Zota led?a study?that showed a connection between phthalate exposure and fast-food restaurants. The new study expands on this research by showing that the link persists even when eating at other types of establishments, such as sit-down restaurants and cafeterias, she said."We first used this methodology to focus on fast food and found some striking associations between recent fast food consumption and phthalate exposure," Zota said. "And now, we extended that to see if the findings were unique to fast food, or how do they compare to other food outlets that may reflect other types of food processing and manufacturing systems?"Last year,?a report found high concentrations of phthalates in macaroni and cheese mixes, which prompted a push for additional regulation of the chemicals in food. Although the US Food and Drug Administration monitors levels of phthalates in a number of cosmetics, it does not regulate its presence in food or beverage products."Policy would need to focus on reducing phthalate exposures in food production processes. Food manufacturers would need to know about sources of contamination and work to reduce these," Sathyanarayana said. "The other way to approach it is to either reduce or ban phthalate use in food manufacturing."The good news, though, is that phthalates linger in the body for only about a day. Changing your eating habits and consuming more home-cooked meals could therefore have almost immediate health benefits, according to Zota."Preparing food at home may represent a win-win," Zota said. "Home-cooked meals can be a good way to reduce sugar, unhealthy fats and salt, and this study suggests that they may not have as many harmful phthalates as restaurant meals."The other important point is that these chemicals are ubiquitous in the environment," she added."So, to really reduce everyone's exposure to these potentially harmful chemicals, we need systemic changes to how our food is produced and transported, and that's going to require changes in policy as well as market-based solutions." 5643
